Abstract
Raman spectroscopy provides a means for the detection and identification of pictorial materials on artworks. As a non-destructive, applicable in situ and non-ambiguous technique, it is one of the most preferred to analyse the pigmentation of any kind of artwork: from paintings [1] and papyrus [2] to polychromes on woods [3]. A common problem, however, is lack of spatial resolution on some systems due to large focal distances, which degrades the theoretical high resolution of the system, which in...
